SCR-23 Air Route Surveillance Radar (ARSR)
The SCR-23 L-band PSR is an unattended Air Route Surveillance Radar with high reliability. Its detection range is beyond 420km for civil and military aircrafts below the height of 18000m.
l Advanced system: high repetition frequency for blind filling, frequency diversity, selectable linear / circular
polarization and independent weather channel to realize strong target detection in complex environment.
l Stable software platform: Linux OS, highly-stable software to support the customizing requirement.
l Precise processing: flexible parameters during signal processing, plot processing and track processing, and
parameter adjustment with practical situation to optimize the radar performance.
l Strong anti-jamming capability: various anti-interference methods including low side lobe antenna, large
dynamic range receiver, anti-asynchronous interference, anti-saturation interference, anti-second trip
echo, CFAR, original echo processing, plot filter and special section processing.
l High reliable mode: fail-soft system and seamless switch design to ensure fully automatic recording and reporting
for 24h continuous operation.
l Rich test performance: with the rich fault detection and test system, accurate location, fault diagnosis and clearstatist ical
report forms, it can provide the real-time report of plot, track, data quality and radar performance.
